Hot Rolled & Cold Drawn Incoloy 800H Round Bar UNS N08810 Nickel Alloy Bright Bars

UNS N08810, commonly designated as Incoloy 800H, is a premium nickel-iron-chromium alloy round bar engineered for exceptional performance in high-temperature and corrosive environments. Available in hot rolled and cold drawn (bright bar) variants, this alloy combines robust mechanical strength, superior corrosion resistance, and structural stability—making it a cornerstone material in industries demanding reliability under extreme conditions. Whether for chemical processing equipment or power generation components, UNS N08810 round bars deliver consistent performance backed by rigorous material standards.

Core Properties of UNS N08810 (Incoloy 800H) Alloy

The exceptional performance of UNS N08810 stems from its precisely balanced chemical composition and austenitic face-centered cubic lattice structure. Its controlled carbon content (0.05-0.10%) and optimized aluminum-titanium ratio (0.85-1.20% combined) enhance creep resistance and structural stability at elevated temperatures, distinguishing it from standard 800-series alloys . Below is a detailed breakdown of its key properties:

1. Chemical Composition (Weight %)

 
Element Minimum Maximum Role
Nickel (Ni) 30.0 35.0 Enhances stress corrosion cracking resistance in aqueous environments
Chromium (Cr) 19.0 23.0 Provides oxidation, carburization, and pitting corrosion resistance
Iron (Fe) Balance Balance Base metal ensuring structural integrity
Carbon (C) 0.05 0.10 Improves high-temperature creep and rupture strength
Manganese (Mn) - 1.50 Aids in hot workability
Silicon (Si) - 1.00 Supports oxide film formation for corrosion protection
Copper (Cu) - 0.75 Minimized to avoid compatibility issues in harsh chemicals
Sulfur (S) - 0.015 Reduced to prevent brittleness
Aluminum (Al) 0.15 0.60 Enhances oxidation resistance with titanium
Titanium (Ti) 0.15 0.60 Stabilizes austenitic structure and prevents sensitization

2. Physical & Mechanical Performance

Property Specification Notes
Density 8.0 g/cm³ Consistent across hot rolled and cold drawn variants
Melting Point 1350-1400°C Suitable for high-temperature processing and service
Tensile Strength (Rm) 450 N/mm² (min) Maintained even after long-term exposure to 600°C+
Yield Strength (Rp0.2) 180 N/mm² (min) Ensures structural stability under load
Elongation (A5%) 35% (min) Enables formability for complex components
Oxidation Resistance Up to 1000°C Forms a protective chromium oxide layer

Hot Rolled vs. Cold Drawn UNS N08810 Round Bars

UNS N08810 round bars are manufactured via two primary processes—hot rolling and cold drawing—each producing distinct characteristics tailored to specific applications. The table below compares their key attributes:
 
Feature Hot Rolled UNS N08810 Round Bar Cold Drawn (Bright Bar) UNS N08810
Surface Finish Black, scaled, or pickled; matte texture Bright, smooth, mirror-like (Ra ≤ 0.8μm)
Diameter Range 10-200mm (standard); larger sizes on request 3-100mm; tighter tolerances for precision applications
Dimensional Tolerance ±0.5mm ±0.1mm
Mechanical Properties Moderate hardness; excellent ductility Higher hardness (150-180 HB); enhanced tensile strength
Key Advantages Cost-effective; ideal for heavy machining Ready for direct assembly; reduces post-processing
Typical Applications Furnace components, structural supports Precision shafts, valve stems, instrument parts

Processing & Fabrication Capabilities

UNS N08810 round bars offer exceptional workability, supporting diverse manufacturing needs across industries:
 
  • Hot Working: Processable at 871-1232°C (1600-2250°F) for forging, bending, and shaping, followed by air cooling to retain mechanical properties .
  • Cold Working: Cold drawing enhances surface finish and dimensional accuracy; annealing at 982°C for 15 minutes restores ductility after extensive cold forming .
  • Welding: Compatible with standard stainless steel welding techniques (TIG, MIG, SMAW) without pre-heating; post-weld annealing is optional for critical corrosion-resistant applications .
  • Machining: Machinable with carbide tools; coolant use is recommended to prevent work hardening .

Industrial Applications & Use Cases

The unique combination of high-temperature strength and corrosion resistance makes UNS N08810 round bars indispensable in demanding sectors:
 
  • Chemical & Petrochemical: Sulfur-containing atmosphere equipment, nitric acid condensers, and 醋酐裂化 tubes—leveraging resistance to both oxidative and reductive media .
  • Power Generation: Heat exchanger tubes, steam generator components, and gas turbine parts—withstanding 600-700°C operating temperatures without creep deformation .
  • Nuclear Industry: Condenser systems and reactor auxiliary piping—valued for metallurgical stability and radiation resistance .
  • Manufacturing: Furnace fixtures, carburizing equipment, and heating element sheathing—resisting oxidation and carburization in high-heat environments .

Quality Assurance & Standards Compliance

Our UNS N08810 round bars adhere to global industry standards, including ASTM B408 (for nickel alloy bars) and ASME SB408, ensuring consistency in composition and performance. Each batch undergoes rigorous testing:
  • Chemical analysis via X-ray fluorescence (XRF)
  • Mechanical testing (tensile, yield, elongation)
  • Non-destructive testing (ultrasonic for internal defects)
  • Dimensional inspection with precision calipers

Why Choose UNS N08810 Over Alternatives?

Compared to similar alloys like UNS N08811 (Incoloy 800HT), UNS N08810 offers a cost-effective balance of performance for applications below 700°C. While 800HT excels at higher temperatures, UNS N08810 delivers superior value for most industrial heat-resistant needs . Its resistance to sulfur-containing atmospheres also makes it preferable to 304 stainless steel in chemical processing .
 
Whether your project requires the cost-efficiency of hot rolled bars or the precision of cold drawn bright bars, UNS N08810 (Incoloy 800H) round bars provide reliable performance in the world’s most challenging environments.
